I run HI-Safe to check my UP Board DIO, but it showed that cann't read DIO3, DIO5 and DIO8 value. And also showed message "Hardware not ready, please check bios setting". What's wrong?
Please reboot and go to BIOS settings, to disable I2C #2 and HSUART #1 in below BIOS path
Advanced --> HAT Configuration
